When you are health conscious, you must learn about and understand quality seed oils. Identifying and selecting high-quality seed oils is crucial for maximizing health benefits while minimizing risks. Seed oils are in most processed foods. With so many options available, it’s extremely important to know what to look for when shopping for oils. This guide provides the characteristics of seed oils, the impacts on your health, and tips for selecting the healthiest option.
Understanding Seed Oils
Seed oils are extracted from the seeds of various plants. The plants most common to us are safflower, corn, sunflower, and canola. These are highly processed oils used in cooking, baking, and food manufacture because of their versatility, affordability, and impact on the shelf life of processed foods. Lesser-known seed oils, cottonseed, rice bran, soy, and grapeseed oil, are also commonly found in most highly processed products in stores. These eight oils are considered the “Hateful Eight” when discussing nutrition. They’re typically refined using high heat processing and chemically treated for shelf stability.
Identifying Quality Seed Oils – What You Need to Know
Key Factors to Consider
- Look for Cold-Pressed or Expeller-Pressed: The extraction method of high-quality seed oils is generally through cold-pressing or expeller-pressing methods. These methods preserve more nutrients, color, and flavor by avoiding high temperatures and chemicals. Cold-pressed oils, in particular, retain the antioxidants and benefits as compared to the refined oils. Although refined oils have a longer shelf life and require a higher temperature before smoking, the refinement process often strips the oils of essential nutrients while introducing chemical residues.
- Check for Organic Certification: Organic oils are less likely to be genetically modified and are often produced without harmful chemicals. This ensures you’re getting a cleaner product.
- Avoid Trans Fats: Quality seed oils maintain a balance of omega-3 to omega-6 fatty acids. Always check for “hydrogenated” or “partially hydrogenated” oils on the label. These oils generally contain excessive omega-6s and are linked to various health issues, including inflammation and heart disease. Instead, use oils with higher omega-3s, such as flaxseed, which support heart and brain health.
- Packaging Matters: Choose oils in dark glass bottles or tin containers to protect them from light, which can cause them to degrade. Storage in a cool, dark place further preserves their quality. When buying in stores, opt for quality seed oils sold in dark glass bottles. Seed oils stored on shelves in clear plastic bottles and under fluorescent lighting are prone to light and heat oxidation compromising the freshness and possibly promoting free radical formation.
Impact of Seed Oils on Health
The health effects are largely dependent on the type of seed and the processing method.
- Omega-6 fatty acids are essential to overall health, but an excessive amount in the balance to omega-3s can promote inflammation. So it is crucial to balance the omega fatty acids to maintain optimal health.
- Refined or Highly processed seed oils usually contain trans fats and commonly lack the beneficial nutrients. This has the potential to increase the risk of chronic diseases.
- Unrefined, quality seed oils, on the other hand, retain the nutrients, vitamins, and antioxidants. These protect the health benefits when consumed in moderation.
Note: It’s worth advising that not all omega-6 fats are inflammatory. Several human trials indicate that the primary Omega-6 in many seed oils, Linoleic acid (LA), has been shown to reduce LDL cholesterol while supporting cardiovascular health. And while this may be plus on the side of ingesting otherwise harmful seed oils, consumption of these oils should be in moderation and not used in cooking due to oxidation.
Additionally, in an article published by the American Heart Association (AHA) (Omega-6 Fatty Acids and Cardiovascular Disease: Are We Getting Closer to the Truth?, 20 May 2019), it stipulates replacing saturated fats with polyunsaturated fats (particularly linoleic acid) can actually reduce the risk of heart disease. But when these oils are repeatedly heated or reused (restaurant and fast food or personal frying), or stored improperly, the issue of the harmful effects arises. The AHA goes on to state “…this latest meta-analysis at least provides a degree of certainty and, therefore, further comfort that an increase in LA intake within the range advocated by the American Heart Association has no harms associated with it.”
Identifying Healthy, Quality Seed Oils
- Read labels. Look for terms like “cold-pressed,” “unrefined,” or “extra virgin,” which signify healthy seed oils. Terms such as “hydrogenated” or “partially hydrogenated” indicate refined, highly processed seed oils.
- Check for certifications. Certifications listed on the label—for instance, USDA—indicate that the oils meet specific quality standards. But don’t rely solely on the certification.
- Be leery of terminology such as “vegetable oil.” This terminology is ambiguous. Failure to list the type of seed oil indicates it may contain a mixture of low-quality, highly refined seed oils.
- Watch out for “light” or “pure.” These terms on oil labels can refer to highly processed oils that lack nutritional value.
Recommended Quality Seed Oils
- Extra Virgin Olive Oil: This oil is rich in antioxidants and healthy fats, making it ideal for salad dressings and low-heat cooking.
- Avocado Oil: It has a high smoke point. So use avocado oil for frying and roasting while providing heart-healthy benefits.
- Flaxseed Oil: Best used in dressings and smoothies, this oil is an excellent source of omega-3 fatty acids.
In addition, macadamia nut oil, with its buttery flavor and incredible omega balance, and sesame oil, in particular the unrefined type used in Asian dishes, are considered healthy alternative quality seed oils.
How do you incorporate Quality Seed Oils into your diet?
Always use oils in moderation. Even healthy seed oils are calorie-dense, so you should use them sparingly. If you are ingesting an excess of Omega-6s, balance them with Omega-3-rich foods like fatty fish (salmon, mackerel, sardines, tuna, and herring, for instance), flaxseed, walnuts, or healthy, quality seed oils. Use unrefined seed oils in salads, drizzle over your meal, or cook with quality seed oils. Use avocado oil in cooking. It has a higher smoke point than other healthy seed oils. The natural flavor of these can really enhance the taste of food while adding the benefit of balancing omega-6s in your diet.
An important side note: Do not reuse cooking oils. When oils, even healthy, high-quality seed oils, are reheated, oxidation occurs, possibly producing toxic byproducts, and those byproducts are linked to a wide variety of health issues. Reheating oil is why fried fast food is so unhealthy. For frying, try stable fats such as avocado oil, ghee, or even coconut oil; still, the key is moderation in the use of oils.
What Does Research Tell Us?
According to the National Institute of Health (NIH) in their Omega-3 Fatty Acids, Fact Sheet for Health Professionals, published (updated July 18, 2022), “Some researchers propose that the relative intakes of omega-6s and omega-3s—the omega-6/omega-3 ratio—may have important implications for the pathogenesis of many chronic diseases, such as cardiovascular disease (CVD) and cancer, but the optimal ratio—if any—has not been defined.”
They (NIH) continue and state that the ratio is thought to be somewhere between 1:1 and 4:1 (Omega-6 to Omega-3). However, in today’s terms some highly-refined oils increase the intake ratio to 16:1. To balance the high concentration of Omega-6s in the common diet it is, therefore, very important to incorporate quality seed oils with Omega-3s to put the Omegas back in balance.
An additional note: The World Health Organization (WHO) notes that the total intake of PUFAs (short for polyunsaturated fatty acid) should not exceed 11 percent of daily energy intake. Modern diets surpass that level by far! The key to restoring a healthy omega ratio is to make substitutions whenever possible since total elimination is not realistic.
Want a Bonus? Here are just a couple of recipes and substitutions with the use of quality seed oils :
- Instead of using vegetable oil in salad dressings, substitute olive oil or walnut oil
- When baking, swap out canola oil in favor of avocado oil or melted coconut oil
- For a cold omega-3 boost, try drizzling flaxseed oil over smoothies or oatmeal
- In quick sautés, switch sesame or peanut oil for soybean oil and enhance the flavor
